If you need something stronger than our Chromoly retainers, our Titanium retainers are just what you need. When you upgrade from steel to Titanium valve spring retainers you gain speed and power, because LCE Titanium retainers are lighter and stronger than steel. Additionally, our Titanium design gives you confidence; no longer will you be preoccupied with splitting a retainer and tearing up an engine when turning over 8,000 RPM. Titanium retainers are American made from space age material. Titanium is less than half the weight and ten times stronger than the factory steel retainer, these Titanium retainers allow you to use high lift cams without the chance of failure. From a standing idle to the most extreme rpm, our Titanium retainers perform flawlessly, without compromise. For use only with our Pro Dual Valve Springs. Set of 8.
